Blumeriella Kerriae
''Blumeriella kerriae'' is a species of fungus in the family Dermateaceae. Since 2014, the Royal Horticultural Society in the UK has received reports from gardeners and horticulturalists of damage to plants of the shrub ''Kerria japonica''. Symptoms include multiple red spots on leaves and lesions on the stems, resulting in defoliation A defoliant is any herbicidal chemical sprayed or dusted on plants to cause their leaves to fall off. Defoliants are widely used for the selective removal of weeds in managing croplands and lawns. Worldwide use of defoliants, along with the ... and eventual death. It has been determined that this infection is caused by the fungus ''Blumeriella kerriae'', which is specific to the '' Kerria''. This highly contagious disease, known in English as ''Kerria'' twig and leaf blight, was known in the U.S. but had not previously been observed on British plants. It is regarded as a serious threat to the cultivated ''Kerria'' plants, which are popula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gardener
A gardener is someone who practices gardening, either professionally or as a hobby. Description A gardener is any person involved in gardening, arguably the oldest occupation, from the hobbyist in a residential garden, the home-owner supplementing the family food with a small vegetable garden or orchard, to an employee in a plant nursery or the head gardener in a large estate. Garden design and maintenance The garden designer is someone who will design the garden, and the gardener is the person who will undertake the work to produce the desired outcome. Design The term gardener is also used to describe garden designers and landscape architects, who are involved chiefly in the design of gardens, rather than the practical aspects of horticulture. Garden design is considered to be an art in most cultures, distinguished from gardening, which generally means ''garden maintenance''. Vita Sackville-West, Gertrude Jekyll and William Robinson were garden designers as well as garden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerria (plant)
''Kerria japonica'', commonly known as Japanese kerria or Japanese rose, is a deciduous, yellow-flowering shrub in the rose family (Rosaceae), native to China, Japan and Korea. It is the only species in the genus Kerria. In the wild, it grows in thickets on mountain slopes. Japanese kerria has been used for medicine and is also planted in gardens. A double-flowered cultivar, ''K. japonica'' 'Pleniflora', is commonly called bachelor's buttons. Name The genus name ''Kerria'' is also a common name for the species (Kerria). It is named after Scottish gardener William Kerr, who introduced the Japanese kerria cultivar 'Pleniflora'. It is sometimes known by the Japanese ''yamabuki'' (, Chinese pronunciation of characters ''shānchuī'') (= "mountain butterbur" or "mountain breeze") or the Chinese ''dìtáng (huā)'' ().

Defoliation
A defoliant is any herbicidal chemical sprayed or dusted on plants to cause their leaves to fall off. Defoliants are widely used for the selective removal of weeds in managing croplands and lawns. Worldwide use of defoliants, along with the development of other herbicides and pesticides, allowed for the Green Revolution, an increase in agricultural production in mid-20th century. Defoliants have also been used in warfare as a means to deprive an enemy of food crops and/or hiding cover, most notably by the United Kingdom during the Malayan Emergency and the United States in the Vietnam War. Defoliants were also used by Indonesian forces in various internal security operations. Use and application A primary application of defoliants is the selective killing of plants. Two of the oldest chemical herbicides used as defoliants are 2,4-Dichlorophenoxyacetic acid (2,4-D) and 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T). 2,4-D and 2,4,5-T are absorbed by broad-leafed plants, k ...

Plant Stem
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The stems ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesion
A lesion is any damage or abnormal change in the tissue of an organism, usually caused by disease or trauma. ''Lesion'' is derived from the Latin "injury". Lesions may occur in plants as well as animals. Types There is no designated classification or naming convention for lesions. Since lesions can occur anywhere in the body and the definition of a lesion is so broad, the varieties of lesions are virtually endless. Generally, lesions may be classified by their patterns, their sizes, their locations, or their causes. They can also be named after the person who discovered them. For example, Ghon lesions, which are found in the lungs of those with tuberculosis, are named after the lesion's discoverer, Anton Ghon. The characteristic skin lesions of a varicella zoster virus infection are called '' chickenpox''. Lesions of the teeth are usually called dental caries. Location Lesions are often classified by their tissue types or locations. For example, a "skin lesion" or a " bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horticulturalist
Horticulture is the branch of agriculture that deals with the art, science, technology, and business of plant cultivation. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns. The study and practice of horticulture have been traced back thousands of years. Horticulture contributed to the transition from nomadic human communities to sedentary, or semi-sedentary, horticultural communities.von Hagen, V.W. (1957) The Ancient Sun Kingdoms Of The Americas. Ohio: The World Publishing Company Horticulture is divided into several categories which focus on the cultivation and processing of different types of plants and food items for specific purposes.

Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Sue Biggs CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discoveries, to enc ...
